LED lighting assembly structure
Abstract
An LED lighting assembly structure includes a lamp housing, and
an end cap. The lamp housing includes at least one slot. The end
cap includes a lug cap, at least one through-hole, and at least one
reinforcing rib, and at least one fastener. The reinforcing rib and
the through-hole are partially coincident with each other in a
cross section perpendicular to the central axis of the
through-hole. When the fastener is screwed into the through-hole
and the slot, it may either cut into the reinforcing rib, or the
reinforcing rib is pressed against the lug cap, or both the
reinforcing rib is pressed against the lug cap and the fastener
cuts into the reinforcing rib. As a result, the strength between
the fastener and the lamp frame is improved, and it is possible to
make the lamp house smaller and thinner, which is advantageous in
reducing the volume of the entire lamp.

Description
RELATED APPLICATION
This present application claims benefit of the Chinese Application,
CN201511029668.X, filed on Dec. 31, 2015.
BACKGROUND
1. Technical Field
The present application relates to lighting equipments, and more
particularly to an LED lighting assembly structure.
2. Description of the Related Art
Light emitting diode (LED) is growing in popularity due to
decreasing costs and long life compared to incandescent lighting
and fluorescent lighting. Recently, a number of LED lighting
apparatuses have been designed to replace the halogen apparatus, as
well as other traditional incandescent or fluorescence lighting
apparatuses. In some places such as exhibition halls, jewelry
stores, museums, supermarkets, and some home lighting, such as
large villas, will use a lot of LED lamps. With the LED lamps,
especially the large-scale use of strip LED lamps, its rapid
assembly and quality improvement is regarded as one of the
effective ways to reduce costs.
Therefore, it is necessary to provide an LED lighting assembly
structure which can be rapidly assembled and has high quality.
BRIEF DESCRIPTION OF THE DRAWINGS
Many aspects of the embodiments can be better understood with
references to the following drawings. The components in the
drawings are not necessarily drawn to scale, the emphasis instead
being placed upon clearly illustrating the principles of the
embodiments. Moreover, in the drawings, like reference numerals
designate corresponding parts throughout two views.
FIG. 1 is an exploded schematic view of a LED lighting assemble
structure according to an embodiment.
FIG. 2 is a schematic view of an end cap of the LED lighting
assemble structure of FIG. 1.
FIG. 3 is a cross section view of the LED lighting assemble
structure of FIG. 1 taken along the line of A-A.
DETAILED DESCRIPTION
The present application is illustrated by way of example and not by
way of limitation in the figures of the accompanying drawings. It
should be noted that references to "an" or "one" embodiment in this
application are not necessarily to the same embodiment, and such
references mean at least one.
Referring to FIG. 1-FIG. 3, an LED lighting assembly structure 100
according to an embodiment are shown. The LED lighting assembly
structure 100 includes a lamp housing 10, an end cap 20 interposed
in the lamp housing 10, and at least one fastener 30 disposed in
the lamp housing 10 and the end cap 20. It is of course understood
that the LED lighting assembly structure 100 also includes other
functional modules, such as a wire plug-in module, a circuit board,
an LED chip module, and so on, which are not the subject of the
present invention and will not be described in detail herein.
The lamp housing 10 may is of strip shape, and can be made of metal
materials to facilitate heat dissipation of the entire lamp. In the
present embodiment, the lamp housing 10 is of an elongated
structure and is extruded and is made of aluminum alloy. The lamp
housing 10 includes at least one slot 11 disposed therein.
Typically, the lamp housing 10 is provided with two slots 11. The
two slots 11 is configured not only to assemble the end cap 20 but
also to mount a watertight seal, lampshade, or the like. In order
to make the entire lamp small, such as very thin or very light, the
wall thickness of the lamp housing 10 is usually very thin.
Therefore, the parameter of the slot 11 is also small to achieve
the above-purpose. Further, the diameter of the fastener 30, which
is used to assemble the end cap 20, may have no large size because
too much will damage the lamp housing 10 and too little will cause
screw loose. In result, it makes that it is difficult to complete
assembly or the product has a low quality.
The end cap 20 includes a body 21, a lug cap 22 extending from the
body 21, at least one through-hole 23 opened on the body 21, and at
least one reinforcing rib 24 provided between the through-hole 23
and the lug cap 22. The end cap 20 is made of plastic or resin
materials. In order to avoid electric leakage and complicated
structure, the end cap 20 is integrally molded and made of resin or
plastic materials for ease of manufacturing and molding. The lug
cap 22 extends along the axial direction of the lamp housing 10 and
is mounted on the slot 11 for covering a gap among the end cap 20,
the lamp housing 10, and the lampshade. In order to reinforce the
strength of the assembled structure, the two free ends of the lug
cap 22 along the axial direction of the lamp housing 10 are
inserted into the opening of the slot 11. The specific shape of the
lug cap 22 varies with that of the lamp housing 10 and the
lampshade to engage the gap between the lamp housing 10 and the
lampshade. The through-hole 23 is adapted to fit the fastener 30
and the axis of the through-hole 23 is coincident with the
extension direction of the slot 11. In the present embodiment,
since the lamp housing 10 has two the slots 11, the end cap 20 also
has two through-hole 23 correspondingly. The diameter of the
through-hole 23 should be equivalent to that of the fastener 30.
The reinforcing ribs 24 extend from the body 21 along the extending
direction of the lamp housing 10 and are arranged at the edges of
the through-hole 23. In a cross section perpendicular to the
central axis of the through-hole 23, the through hole 23 and the
reinforcing ribs 2 interfere with each other. The interference of
the through-hole 23 with the reinforcing ribs 24 means that the
through-hole 23 are partially coincident with the reinforcing ribs
24 respectively in the direction along the central axis of the
through-hole 23. The reinforcing ribs 24 may be seamlessly
connected to the lug cap 22 or be spaced apart from the lug cap 22.
In the present embodiment, the reinforcing ribs 24 are spaced apart
from the lug cap 22 respectively.
The fastener 30 may be a screw, a plug, a stud, or the like. When
the fastener 30 is threaded through the through-hole 23 and screwed
into the slot 11 of the lamp housing 10, it can be cut into the
through-hole 23, the slot 11, and the reinforcing ribs 24. When the
fastener 30 is the plug and is inserted or threaded into the
through-hole 23 and the slot 11, the reinforcing rib 24 will be
pressed against the lug cap 22 by the fastener 30. In the present
embodiment, the fastener 30 is a tapping screw. When the fastener
30 is threaded through the through-hole 23 and screwed into the
slot 11, not only the fastener 30 cuts into the reinforcing rib 24
but also the reinforcing rib 24 is pressed against the lug cap 22
thereby.
During assembly, when the fastener 30 is screwed into the
through-hole 23 and the slot 11 of the lamp housing 10, it may
either cut into the reinforcing rib 24, or the reinforcing rib 24
is pressed against the lug cap 22, or both the reinforcing rib 24
is pressed against the lug cap 22 and the fastener 30 cuts into the
reinforcing rib 24. As a result, the strength between the fastener
30 and the lamp frame 10 is improved, and it is possible to make
the lamp house 10 smaller and thinner, which is advantageous in
reducing the volume of the entire lamp.
While the disclosure has been described by way of example and in
terms of exemplary embodiment, it is to be understood that the
disclosure is not limited thereto. To the contrary, it is intended
to cover various modifications and similar arrangements (as would
be apparent to those skilled in the art). Therefore, the scope of
the appended claims should be accorded the broadest interpretation
so as to encompass all such modifications and similar
arrangements.
